You can see a rough development roadmap in the Milestones sections. It is open for changes and input from the community, your ideas and questions are welcome.
Release versions will be created on a regular basis, every couple of weeks latest.
Every code change, whether it's a new feature or a bugfix, will be done on the main branch.
Until 2.0 is widely adopted, the 1.x branch will receive (critical) bug and security fixes.
